NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented June 8, 1915.

Application filed April 2, 1914. Serial No. 829,102.

invention is to devise a simple and inexperr' sive bottle having provided in the neck thereof a highly efficient means for preventing the refilling of the bottle without the destruction of the same, such means being adapted, at the same time, to aiford a perfectly free exit for the liquid from the bottle when the same is tilted in the usual manner for pouring. I attain this object by the means illustrated in the accompanying drawings, in which Figure 1 is a view of the neck of my bottle in upright position, showing the parts assembled therein, partly in section and partly in elevation. Fig. 2 is a similar view to Fig. 1, but shown tilted as for pouring. Fig. 3 is a perspective view of the stopper. Fig. 4 is a perspective view of the valve seat. Fig. 5 is a perspective view of the locking member. Fig. 6 is a perspective view of the valve.

Similar figures of reference indicate similar parts throughout the several views.

The body of my bottle may be constructed of glass or other similar material and may be of any shape and construction.

1 is the neck of my bottle, which may be formed integrally with the body as shown in Fig. 1 or it may-be made separate therefrom and attached to the body after filling, if desired. The neck 1 is tapered downward, that is, it is gradually diminished in diameter from its upper end to the point where it merges into the body, all as shown in Fig. 1. It is not necessary, of course, for the outside of the neck to be so tapered, provided the interior of the neck is formed as described.

Disposed in the neck 1 in proximity to the neck and to be firmly secured therein by glass cement or other similar means.

3 is a non-return valve adapted to normally engage the valve seat 2, asshown in Fig. 1, to tightly close the valve seat open ing 4 when the bottle is held in the upright position, this valve being formed preferably as shown in Figs. 1, 2 and "6 and provided'with a cavity 5 in its upper end.

6 is a locking member extending between the valve 3 and the stopper 9, as shown in Fig. 1, the purpose of this member being to practically lock the valve 3 in its seat 2, when the bottle is in the upright position or lying on its side and thus prevent the bottle from being refilled when in either of those positions. This locking member 6 is formed preferably as shown in Figs. 1, 2 and 5, and when the several parts are assembled the lower pointed end of this member 6 normally rests in the cavity 5 while its length is such that its upper end just clears ilzrhe point of the stopper 9, all as shown in 8 is an inwardly extending bore provided in the upper end of the member 6 whereby it is adapted to slip over and engage the point of the stopper 9 and allow for the valve 3 leaving the valve seat 2 sufficiently to permit of the liquid flowing therethrough when the bottle is tilted, all as shown in Fig. 2.

9 is the bottle stopper, formed preferably as shown in Figs. 1, 2 and 3, that is, having a cap or disk 10 adapted to fit snugly into point where its extremity is just clear of the upper end of the locking member 6, when the bottle is in the upright position,

' as shown in Fig. 1.

12 and 13 are segmental disks formed integrally with the stem 11 at different heights thereon, as shown in Figs. 1, 2, andS, the respective diameters of the disks being such that they will fit snugly into the taper of the neck when the stopper 9 is placed in its assembled position, the disks also being cemented to the neck to further secure the stopper in place. These disks are arranged approximately as shown in Fig. 8, and are joined on one side of the stem by the portion 14, the outer edge of which fits snugly against the inside of the neck 1, being also cemented thereto.

15 is a portion cut out of the cap 10, thus providing an opening when the bottle is assembled through which the liquid may be poured out. The opening may be sealed by a piece of cork or any other similar means suitable for the purpose.

It will be understood, of course, that the various parts, although preferably constructed of glass, may be made of any other suitable material.

Having thus indicated the principal parts of my invention T will now describe the manner in which it operates. The bottle is filled with liquid through the neck 1 in the usual manner, after which the valve seat 2 is disposed as shown in the neck and firmly cemented therein. The valve 8 is then placed in the seat 2, the locking member 6 is placed with its lower point resting in the cavity 5, and finally the stopper 9 is inserted and cemented in'position with the cap 10 level with the upper end of the neck and the point of the stem 11 just clear of the upper end of the locking member 6, as shown in Fig. 1. The opening formed by the cut out portion 15 may then be sealed and the bottle capped in the usual manner. When it is desired to obtain the contents of the bottle, the cap, which it is not deemed necessary to illustrate, is removed and the seal broken, after which the liquid may be poured out by tilting the bottle as shown in Fig. 2 since when this is done the locking member 6 slips down over the inner end of the stopper and the valve 3 leaves the seat 2, allowing the liquid to flow through the opening 4 past the valve 3 and round the stem 11 and disks 12 and 13 to the opening formed by the cut out portion 15 of the disk 10. On returning the bottle to a substantially upright position, the valve 3 immediately drops into place on the seat 2, tightly closing same, since it is held down thereon and locked by the member 6 which immediately assumes its normal position between the inner end of the stem and the valve 3, as shown in Fig. 1, thus absolutely preventing the downward passage of liquid into the bottle and at the same time insuring that no evaporation of any remaining contents will occur.

It will be seen further on referring to the drawings, that the construction of the stopper 9 is such that it is impossible to intro duce any instrument into the neck in an attempt to tamper with the valve 3, and also that the relative arrangement of parts precludes the possibility of the bottle being filled by means of vacuum or otherwise unless the neck and the various parts are mutilated to such an extent as to make it evident that the bottle has been surreptitiously refilled.

It will, of course, be understood that the neck 1 may be made separate from the body of the bottle, in which case, the parts would be assembled and the neck prepared ready for attachment to the body of the bottle, which, in this event, would be filled before the cementing of the prepared neck thereto.

What I claim as my invention is 1. The combination with a bottle neck, of a valve seat permanently secured into the neck at the lower end thereof, a non-return valve co-acting with said seat and having a cavity in its upper end, the body of said valve being substantially cone-shaped, and its upper end being enlarged to a proximately fit the said neck, a substantial y coneshaped locking member the lower end of which is normally engaged in the cavity of the said valve and having a bell mouthed inwardly extending bore in its upper end, a stopper of substantially disk formation provided with an exit opening and adapted to be permanently secured in the upper end of the neck and having a stem extending centrally therefrom and inwardly to a point in close proximity to the upper end of the said locking member, and segmental disks formed in the said stem and oppositely set thereon at different levels and having their opposite ends on one side of the stem joined by an intervening portion, the said disks and said intervening portion being adapted to fit the taper of the said neck, as and for the purpose specified.

2. The combination with a bottle neck, of a valve seat permanently secured in said neck, and a non-return valve co-acting with said seat, of means for locking and unlocking the said valve when in the upright and tilted positions respectively, said means consisting of a stopper provided with an exit opening permanently secured in the neck and a locking member adapted to extend between the said stopper and said valve when the neck is in the upright or horizontal positions and to slip over the inner end of the said stopper when the neck is tilted for pouring, said intervening portion fitting the ta er and means for preventing the lifting of said of the neck, as and for the purpose speci ed. 10 valve by exteriorly operated means, said Dated at Vancouver, B.
